Shoe upper



FIG. 1 is a front perspective view of a shoe upper showing my new design;

FIG. 2 is a side view thereof; and,

FIG. 3 is a rear perspective view.

The broken lines immediately adjacent to the shaded area define the bounds of the claimed design and form no part thereof. The contrast in shading represents a contrast in appearance only and does not represent any particular color, material, texture or finish. The broken lines showing the remainder of the shoe are for environmental purposes only and form no part of the claimed design. 

CLAIM The ornamental design for a shoe upper, as shown and described.
